The Cowboys have placed the franchise tag on Prescott, Ian Rapoport of NFL Network reports.
With no agreement on a long-term contract, the Cowboys had little choice but to use the tag on Prescott, who now has until mid-July to sign a multi-year deal. Meanwhile, wide receiver Amari Cooper will be able to field offers from other teams, as the recent completion of a new CBA means the Cowboys only have one tag to use this offseason.
